Is Keating is potent as Ayers? No, it's not. There are several reasons why: Keating was largely a dem scandal- tarring such figures as John Glenn, it's more complex, and people react more viscerally to a "terrorist bomber" than to a corrupt banker. So yeah, I think Ayers could be damaging. I think next they'll throw out Khalidi and Wright. Those who say that this has all been covered in the primary are wrong. Lots of people just weren't tuned in during the primaries and this is potent stuff. And it's all the more potent because Obama is a black man with an unusual biography named Barack Obama. No one will ever question McCain's "Americainess". Barack Obama has had to be vigilant about such attacks from the onset of his campaign.
It won't be surprising if Obama starts sinking in the polls and McCain starts rising, due to these attacks. Americans have a xenophobic streak and we're a very reactionary people.
BUT
Having said that, this election will be won by superior strategy. It will be won by the immediate circumstances that impact the lives of voters. It will be won in the trenches by organization and money- which is where all presidential elections are won. Obama and team have demonstrated repeatedly that they understand how to win. Here's an example:

Obama's grass-roots battalion vs. McCain's ragtag platoon
In Wisconsin's blue-collar Paper Valley, the Democrats are banking on an outpouring of volunteers while the Republicans are left with fear itself.
By Walter Shapiro
Oct. 6, 2008 | GREEN BAY, Wis. -- Mid-morning Saturday, the Republican headquarters here in the fiercely contested northeast corner of Wisconsin reflected the somnolent air of the half-empty indoor mall in which it was located. A few Republican stalwarts wandered by to pick up McCain-Palin lawn signs and other GOP campaign paraphernalia. A signboard on the wall announced the target of "878 Doors" on which to knock, but it was evident that most of the canvassing -- the lifeblood of grass-roots organizing and get-out-the-vote drives -- would be done by pairs of high-school students too young to vote.
Two hours later, in contrast, the pulse rate was racing at the local Democratic headquarters as more than 70 political foot soldiers (most of them middle-aged) readied themselves for an afternoon of canvassing, phone calling and scrawling vote-for-Obama postcards to neighbors. On the sidewalk of the down-at-the-heels strip mall, Obama volunteers grilled lunchtime hamburgers and hot dogs as if this were an alcohol-free Packer tailgate party outside of Lambeau Field.
Sometimes in politics, the obvious can be more telling than the subtle. For all the glib talk about how Sarah Palin has energized the conservative base, it is hard to find evidence that the Republicans have papered over their enthusiasm gap here in Paper Valley, a moniker designating the dominant local industry in the Green Bay-Appleton area. "Our volunteer base is getting older and we're trying to turn that around, but it's not easy," concedes Tom Van Drasek, the Republican chairman of Brown County, of which Green Bay is the county seat. "McCain got started late here on the ground -- and we're struggling to catch up."
With the McCain campaign retreating from Michigan into Wisconsin (a state that John Kerry won by a paltry 11,000 votes in 2004), the Paper Valley is scorched-earth political terrain. According to the latest media-monitoring measurement by the University of Wisconsin Advertising Project, the Green Bay area was sixth in the nation in terms of the number of TV spots aired during the second week in September, even though it is the 69th largest media market in the country. John McCain and Barack Obama held Green Bay rallies four days apart in mid-September. As Mark Graul, a Republican strategist who ran the 2004 Bush campaign in Wisconsin, puts it, "John McCain has to win this congressional district
by 10 points in order to win the state." (In 2004, George W. Bush defeated Kerry by 11 points in the heavily Catholic 8th; two-thirds of the district's electorate lives in the Green Bay-Appleton area).
